Tension compression conversion type rubber buffer

Abstract

The invention relates to a tension compression conversion type rubber buffer. The buffer comprises a rubber buffer; a tension rod is arranged at the front end of the rubber buffer, and a tension ring is arranged at the back end of the rubber buffer; a limiting device for controlling the stroke of the buffer is arranged on both sides of the rubber buffer; a fixed mounting plate is respectively arranged at the front and the back ends of the rubber buffer; the back mounting plate is fixed on the tension ring; and the tension rod shaft of the tension rod is sleeved inside the central holes of the rubber buffer, the mounting plates and the tension ring. The tension compression conversion type rubber buffer is simple and reliable in structure, and realizes the tension compression conversion function of a low flow vehicle foldable draft gear; and through the arranged limiting device of stroke, the stroke of the buffer is accurately controlled. Without special interface requirement, the tension compression conversion type rubber buffer can be used as a module and grafted on other similar draw gear structures for use.

Description

technical field [0001] The invention relates to a buffer device for a rail vehicle, in particular to a light-duty coupler tension-compression buffer for a low-floor vehicle. Background technique [0002] There is a certain distance between the floor surface of conventional rail train vehicles and the rail surface, so there are generally higher platforms in the station, and the design of low-floor vehicles minimizes the height difference between the floor and the platform, which is convenient for passengers to ride and saves the construction cost of the platform. , the design of the coupler as a vehicle connecting part should be compatible with the low-floor vehicle system. [0003] At present, the coupler body of the front car of low-floor vehicles generally adopts the Albert coupler, and there is a foldable joint in the middle so that the coupler can be folded to the underframe of the car body under normal operating conditions. The installation space restricts the design of...

Problems solved by technology

[0005] The present invention aims at the above-mentioned shortcomings such as the poor comfort of the existing low-floor vehicle coupler, and provides a tension-compression conversion rubber buffer, which can realize the compression of the buffer through its own structure when the coupler is under tension or compression Absorb energy and realize the control of buffer tension and compression stroke through its own structure
